Why mornings are common
B vitamins play a role in energy metabolism, and many people prefer taking them earlier in the day rather than at night. Taking them with breakfast is an easy, repeatable anchor.
How much they help varies a lot from person to person, so it is best to view them as one part of a balanced routine rather than a quick fix.
A steady morning habit
If mornings are your anchor, a reminder keeps it consistent even on rushed days. Pillog nudges you at your set time, lets you check it off from the notification, and shows your month as a card, all kept on your phone with no account.
Ongoing tiredness can have many causes, so if fatigue is persistent, a doctor is the right person to look into it.
